Amazon Warehousing and Distribution is upstream bulk storage that sits before FBA. You send inventory to an Amazon distribution center. Amazon holds it. When FBA stock runs low, Amazon replenishes automatically or on your command. The goal is simple: keep products in stock without paying FBA storage rates on your entire buffer.
AWD launched in late 2022. Back then it was positioned as a new experiment. Today it is part of Amazon's wider Supply Chain by Amazon ecosystem. It supports auto-replenishment into FBA, manual replenishment when you need tighter control, and distribution to non-Amazon channels like Walmart Fulfillment Services or your own warehouse.
The real question for sellers is not "What is AWD?" It is "Does AWD make financial and operational sense for my catalog?" This guide walks through how AWD works, what it costs, where it helps, and where it creates new risks.
AWD is Amazon's bulk storage layer for third-party sellers. Think of it as a holding zone for inventory that is not yet needed in FBA. You ship large quantities to AWD. Amazon stores the product at a lower monthly rate than FBA. When your FBA stock hits a threshold you define, Amazon moves cases from AWD into fulfillment centers.
AWD is not a replacement for FBA. It is a complement. FBA still handles picks, packs, and ships. AWD handles the buffer inventory you used to keep in a 3PL warehouse or your own facility.
Supply Chain by Amazon is Amazon's umbrella term for logistics services beyond core FBA. It includes AWD for upstream storage, Multi-Channel Fulfillment for non-Amazon orders, Buy with Prime for off-Amazon storefronts, and Amazon Global Logistics for international shipping.
AWD is the storage piece. If you use Amazon's full stack, you might ship product from a manufacturer overseas using Amazon Global Logistics, store the bulk in AWD, replenish into FBA as needed, and use Multi-Channel Fulfillment to send Walmart or Shopify orders from the same inventory pool.
Not every brand needs the full stack. Many sellers use AWD with their own freight forwarder and their own 3PL for non-Amazon channels. AWD is modular.
FBA is short-term storage tied to active listings. It charges higher storage fees, especially during Q4. It picks and ships Prime orders. It enforces inventory limits and charges aged inventory fees if products sit too long.
AWD is long-term storage with no current inventory caps. It charges lower monthly fees. It does not pick or ship orders. It feeds FBA or other distribution points.
MCF is Multi-Channel Fulfillment. It ships inventory stored in FBA to non-Amazon orders. You can use MCF without AWD. You can use AWD to feed MCF inventory. They are separate but compatible.
The typical flow: bulk ships to AWD, AWD auto-replenishes FBA, FBA fulfills Amazon orders, MCF pulls from the same FBA stock to fulfill Walmart or direct sales.
You create a shipment in Seller Central. You choose AWD as the destination. Amazon gives you a distribution center address. You arrange freight from your supplier or warehouse to that address.
AWD currently supports LTL and full truckload shipments. Amazon's current guidance emphasizes seller-arranged or Amazon-partnered transportation. Some seller documentation mentions parcel support, but LTL remains the clearest supported path for large-volume shipments. Verify current shipping method rules in Seller Central before planning your first send.
Each SKU must be packed in its own case. Mixed-SKU boxes are not allowed. Each case gets a label. The truck delivers to the AWD facility. Amazon receives the inventory and logs it in your AWD dashboard.
Processing times at AWD vary. Expect longer windows than FBA parcel receives. Plan buffer stock in FBA while your first AWD shipment checks in.
Once inventory is in AWD, you set replenishment rules. Amazon offers three modes:
Amazon-recommended auto-replenishment: Amazon calculates FBA stock needs based on sales velocity and lead time. When FBA inventory drops below a calculated threshold, Amazon moves cases from AWD into FBA automatically. You set no manual triggers.
Auto-replenishment with quantity limits: You define max quantities per replenishment. Amazon still triggers the moves, but respects your caps. Useful when cash flow or FBA space is constrained.
Manual replenishment: You tell Amazon when to move inventory and how much. No automation. Full control.
Most steady-state SKUs with predictable demand work well on Amazon-recommended mode. Launch products, promo-driven SKUs, or anything with volatile demand should start on manual mode until patterns stabilize.
Replenishment is not instant. Once Amazon triggers a transfer, cases move through Amazon's internal logistics network. Expect days, not hours. Keep enough FBA stock to cover the transfer window.
AWD inventory can distribute to locations outside FBA. Amazon's current documentation lists several supported paths: Walmart Fulfillment Services, your own warehouse or distribution center, wholesalers or distributors, and other US-based sales channels.
This is not Multi-Channel Fulfillment. MCF ships individual orders from FBA. AWD distribution sends bulk cases to a non-Amazon destination. You would use this if you sell on Walmart, manage your own DTC fulfillment, or supply wholesale partners.
Not all AWD users need multichannel distribution. If you only sell on Amazon, stick with FBA replenishment and skip this feature.

Connect With Our TeamAWD charges monthly storage based on cubic feet of space used. Rates vary by region.
Amazon offers two discount programs:
Discounts may stack in some cases. Verify current qualification logic in your Seller Central account. AWD does not charge holiday surcharges the way FBA does. October through December pricing stays flat.
AWD charges a per-case processing fee for receiving inventory and another per-case fee when moving it out. As of March 2026:
Transportation fees cover only AWD-to-FBA transfers. You still pay your own freight to get inventory into AWD initially.
AWD versus FBA storage: FBA storage fees for standard-size products run $0.87 to $1.05 per cubic foot per month during non-peak months (January through September). FBA charges $2.40 per cubic foot per month during October through December. AWD storage at $0.48 to $0.57 per cubic foot looks cheaper than FBA year-round. But FBA includes pick-and-pack capability. AWD is storage only. You also pay processing and transportation fees to move AWD inventory into FBA.
The savings come when you hold large buffer quantities. If you keep six months of inventory for a product, paying AWD rates on the bulk and FBA rates only on near-term stock cuts monthly storage spend.
AWD versus a 3PL: Third-party logistics providers charge storage, receiving, and outbound fees. Rates vary widely by provider, location, and volume. Some 3PLs beat AWD on storage cost. Others charge more but offer prep services, kitting, returns handling, or multichannel fulfillment that AWD does not.
AWD's advantage is integration with FBA. Replenishment is automatic or semi-automatic. You manage everything in Seller Central. A 3PL requires separate systems and coordination. AWD's disadvantage is control. You cannot inspect inventory, run special prep, or rework packaging once it is in AWD. A 3PL offers hands-on access.
If your operation needs custom prep, bundling, or frequent inventory audits, a 3PL still beats AWD. If you run simple case-pack replenishment for standard products, AWD may cost less and require less management.
Run a cost comparison for one representative SKU before committing your full catalog. Calculate:
Add non-financial factors: speed, control, replenishment flexibility, channel fit. The lowest price option is not always the best operational fit.
AWD storage runs about half of FBA storage during non-peak months and less than a quarter of FBA peak-season rates. If you carry large seasonal buys or slow-turning backup inventory, moving that volume out of FBA into AWD cuts monthly storage bills.
Aged inventory fees do not start until inventory hits FBA. The clock does not run while product sits in AWD. For slow movers or test inventory, that delay can matter.
Stockouts kill rank, break ad campaigns, and hand market share to competitors. AWD gives you a replenishment buffer. If demand spikes or inbound shipments delay, your FBA stock can pull from AWD instead of going to zero.
Auto-replenishment reduces the chance you forget to send more inventory. The system monitors FBA levels and triggers transfers before you stockout. Manual replenishment gives you control when you need it. Launch a promo, adjust for a surge, or hold inventory back during a slow period.
Managing replenishment timing across dozens or hundreds of SKUs is tedious. AWD's Amazon-recommended mode automates the math. You review the transfers, but you do not calculate every threshold manually.
For brands with large catalogs and steady demand, this saves operational time. For brands with volatile or seasonal patterns, manual mode may still be smarter.
In 2024, Amazon introduced inbound placement fees. These fees charge sellers when shipments do not match Amazon's preferred distribution across fulfillment centers. The fees add cost and complexity.
Amazon's current AWD positioning states that inventory moving from AWD into FBA does not incur separate inbound placement charges. The transportation fee covers distribution. For high-volume sellers hit hard by placement fees, this can shift the cost equation in AWD's favor.
Verify current placement fee rules in your account. Policy details change and fee structures vary by seller size and shipment type.
Once inventory enters AWD, you cannot touch it. You cannot inspect, relabel, repackage, or pull samples. If you discover a prep error or need to add a compliance label, the product is locked in Amazon's system.
A 3PL lets you walk the warehouse, audit inventory, and make changes. AWD does not.
Auto-replenishment gives Amazon control over transfer timing and quantities. If the algorithm miscalculates demand or moves too much inventory into FBA, you pay higher FBA storage fees. If it moves too little, you stockout. Manual replenishment keeps control, but adds management work.
AWD works best for brands selling primarily on Amazon. If you split volume across Amazon, Walmart, Shopify, and wholesale, you may need more flexible distribution.
AWD supports bulk distribution to non-Amazon channels, but setup and coordination are less mature than what a good 3PL provides. If you need real-time multichannel allocation, AWD may not fit.
AWD does not support order-level fulfillment outside FBA. It is bulk-only. For DTC or wholesale, you still need separate fulfillment infrastructure.
AWD is still newer than FBA. Processing times can be longer. Shipment visibility can be weaker. Some sellers report delayed check-ins, missing inventory, or slow resolution when issues arise.
FBA has problems too, but FBA's scale and maturity generally mean faster resolution paths. AWD is smaller and less proven.
Replenishment windows between AWD and FBA add lead time. Plan buffer stock to cover transfer delays. Do not assume instant restocks.
Not all products qualify for AWD. Amazon's current eligibility rules exclude certain categories and types. Recent updates expanded eligibility to include shoes, expiration-dated products, and some non-sort items, but restrictions remain.
Currently ineligible or restricted:
Mixed-SKU cases are not allowed. Each SKU must ship in separate cases. Size and weight limits apply, though Amazon has expanded beyond the original "standard-size only" constraint. Verify current rules in Seller Central before sending oversize or heavy products.
Expiration-dated products are now eligible, but Amazon requires minimum shelf life at receipt. Check current requirements for your category. Verify eligibility for every SKU before planning a shipment. Rules change and category exceptions exist.

AWD makes sense when you sell mostly or entirely on Amazon, carry large seasonal inventory buys and want lower storage costs, run steady predictable SKUs that fit auto-replenishment, ship standard case packs with no special prep requirements, want to avoid FBA inbound placement fees, and need simple upstream buffering without hands-on inventory access.
Best candidate profile: Amazon-first brand, high volume, stable demand, case-pack simplicity, low touch requirements.
A 3PL beats AWD when you need kitting, bundling, or custom prep services; fulfill orders across Amazon, Walmart, Shopify, and wholesale simultaneously; want physical access to inventory for audits or rework; need returns processing and inspection; run promotions or flash sales requiring rapid inventory moves; or value supplier relationships and hands-on logistics support.
Best candidate profile: Multichannel brand, complex fulfillment needs, high-touch operations, desire for control and flexibility.
Some brands use both. Common hybrid patterns:
Stable SKUs in AWD, complex SKUs in a 3PL: Let Amazon handle replenishment for predictable products. Keep promotional SKUs, bundles, or prep-intensive items with a 3PL.
Seasonal buffer in AWD, active stock in FBA and 3PL: Use AWD for large Q4 buys. Use your 3PL for multichannel fulfillment. Use FBA for Amazon orders.
AWD as primary buffer, 3PL as overflow and prep: Store most inventory in AWD. Use the 3PL for kitting, relabeling, or special projects.
Hybrid models add complexity. Manage them only if the cost or service benefits justify the coordination work.
AWD enrollment is managed through Seller Central. Amazon previously ran an invitation-only pilot. Current access appears more open, though some accounts may still require activation.
To check eligibility and enroll:
If AWD options do not appear in your account, contact Seller Support or your account manager to request access.
Before sending inventory to AWD:
Start with a small test shipment. Validate the process before sending large volumes.
AWD storage is cheaper than FBA storage. But AWD charges processing fees and transportation fees that FBA storage does not. Total cost depends on how long you hold inventory, how often you replenish, and your volume. For large buffer quantities held for months, AWD usually costs less. For fast-turning inventory that ships directly into FBA and sells quickly, FBA-only may cost less. Run a cost model with your actual SKU data before deciding.
No. AWD is upstream storage. FBA is fulfillment. You need both. AWD holds bulk inventory. FBA picks, packs, and ships orders. AWD feeds FBA.
AWD supports bulk distribution to non-Amazon channels like Walmart Fulfillment Services or your own warehouse. But AWD does not ship individual orders outside Amazon. For order-level fulfillment on Shopify or direct sales, use FBA with Multi-Channel Fulfillment or a separate 3PL.
Hazmat products, high-value items, Amazon devices, gift cards, refrigerated products, and other restricted categories are not eligible. Mixed-SKU cases are not allowed. Size and weight restrictions apply, though Amazon has expanded eligibility beyond the original standard-size-only rule. Verify current eligibility for each SKU in Seller Central before shipping.
It depends on your operation. If you sell mostly on Amazon, run simple case-pack replenishment, and want lower storage costs with less management, AWD may fit. If you need multichannel fulfillment, custom prep, returns handling, or hands-on inventory access, a 3PL is better. Many brands use both. AWD for Amazon buffer inventory, 3PL for everything else.
AWD is not a universal solution. It fits specific operations.
Use AWD if: Amazon is your primary or only channel. You carry large buffer inventory and pay high FBA storage fees. Your SKUs fit auto-replenishment patterns. You want integrated replenishment inside Seller Central. You ship standard case packs with no special prep.
Skip AWD if: You need multichannel fulfillment flexibility. You require custom prep, kitting, or hands-on inventory access. Your demand is volatile or promo-heavy and needs tight control. Your products need special handling. You value supplier relationships over automation.
The best path is not always the cheapest. Factor in control, speed, service quality, and risk alongside cost.
AWD interacts with FBA fees, inbound placement logic, forecasting, and supply chain timing. Getting the model wrong can lock inventory in the wrong place, trigger stockouts, or increase total costs instead of lowering them.
If you manage a large catalog, run complex seasonal patterns, or split volume across channels, work with a team that has modeled AWD economics and operations for similar brands. The setup is simple. The tradeoffs are not.
At SupplyKick, we help brands evaluate whether AWD fits their inventory strategy, model the cost implications, and coordinate replenishment timing with ad spend, promotions, and seasonal demand.
